Occurs when a stimulus change immediately follows a response and increases the future frequency of that type of behavior in similar circumstances Reinforcement can increase the frequency (e.g., greetings) of a response, the duration (e.g., walking),latency (e.g., reading), magnitude (e.g., lifting a lever) , and/or topography (e.g., form)

B.F. SkinnerWe reinforce behavior, not people Reinforcement increases behavior, a "reward" may not necessarily have an accelerating effect Preference and Reinforcer Assessments

Occurs when a behavior is followed immediately by the presentation of a stimulus that increases the future frequency of the behavior in similar conditions. Negative Reinforcement Occurs when a behavior is followed immediatelyby removal, termination, or reduction, or postponement of a stimulus that increases thefuture frequency of the behavior in similar conditions Negative Reinforcer.

A stimulus whose termination, reduction, or postponement functions as reinforcement (can be unconditioned or conditioned) Special Note: Negative reinforcement is not punishment The inside of the airplane I am flying is very loud, so, I put my noise canceling headset onScience and Human Behavior B.F.
